What does the refractive index 1.6 1 of Hetian jade represent?

The refractive index of jadeite is the filter color calculated by the filter multiplied by the color behind the transparent surface. Click the color swatch to change the filter color. Click this button to assign a map to the filter color component. Filter or transmission color is the color that passes through transparent or translucent materials (such as glass). You can combine filter colors with volume lighting to create an effect similar to colored lights passing through dirty glass windows. Ray tracing shadows cast by transparent objects will be colored with filter colors. Refractive index—Sets the refractive index (IOR) used for refractive mapping and ray tracing. IOR is used to control the degree of refraction of transmitted light by materials. The refractive index of air is slightly larger than 1.0, and the object behind the transparent object will not be deformed. If the refractive index is 1.5, the object behind it will be severely distorted, just like a glass ball. If the refractive index is slightly lower than 1.0, the object will reflect along its edge, just like a bubble seen from the bottom of the water. The default setting is 1.0. Common refractive indexes (assuming the camera is in air or vacuum) are: material refractive index value vacuum 1.0 (accurate) air 1.0003 water 1.333 glass 1.5 (transparent glass) to 1.7 diamond 2. Usually related to the density of the object; The higher the refractive index, the higher the density of the object. You can also use maps to control the refractive index. The refractive index map always interpolates between 1.0 (refractive index of air) and the set value in the refractive index parameter. For example, if the refractive index is set to 3.55 and the refractive index is controlled by black and white "noise", then the refractive index value rendered on the object will be set between 1.0 and 3.55; This object looks denser than air. On the other hand, if the refractive index is set to 0.5, the same mapping value will be rendered between 0.5 and 1.0, just like the camera is underwater and the object looks thinner than water.
